钢筋混凝土环形截面偏压构件正截面承载力的简化计算

Capacity of Reinforced Concrete Eccentrically Compressive Members with Annular-shaped Cross-section

将沿周边均匀配筋的环形截面用沿腹板高度作均匀配筋的等效工字形截面来代替。在此基础上提出分析钢筋混凝土环形截面偏压构件正截面承载力的简化公式。分析计算结果表明，分析方法和公式便于应用且具足够精度。

A Reinforced concrete annular-shaped section with circumferentially uniformreinforcements is equivalently repiaced by an I-shaped one uniformly reinforced along its webin this paper to simplify the calculation formula of the column capacity with annular-shapedsection. Analytical results show that the method presented is feasible with appropriate accuracy.
